PDO exception when saving context configuration after context feature revert

After reverting a feature that contains scald_context_config components, we get the following exception when submitting the context form on "/admin/structure/scald/image/contexts":

PDOException: SQLSTATE[HY000]: General error: 1364 Field 'data' doesn't have a default value: INSERT INTO {scald_context_config} (context, transcoder, player) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2); Array
